Few years before I purchased this water purifier. It has a nice capacity of 15 liter therefore it is quite reliable. But this is a huge purifier takes lots of space in the kitchen, if you have a small kitchen I wont advice to buy it. But what is problematic is its servicing, in every 2 month this purifier requires servicing which cost not less than Rs.1500. If you skip the servicing you will get muddy black colour water not suitable to drink.
